The entries below contain brief descriptions of the changes in a release, in no particular order. Some of the entries reflect significant new additions, while others represent minor corrections. Although this list is not a comprehensive report of every change we made in a release, it does provide details on the changes we feel Ice users might need to be aware of.

We recommend that you use the release notes as a guide for migrating your applications to this release, and the manual for complete details on a particular aspect of Ice.

Changes in Ice 3.7.0

These are the changes since Ice 3.6.3.

General Changes

  • Added Bluetooth transport plug-in for C++ and Android. The C++ plug-in requires BlueZ 5.40 or later.

  • Dispatch interceptors and ice_dispatch can now handle user exceptions. User exceptions raised by a servant dispatch are propagated to ice_dispatch and can also be raised from the Ice::DispatchInterceptor::dispatch implementation. As a result, the Ice::DispatchStatus enumeration has been removed. See the Ice manual for details on the new dispatch interceptor API.

  • The ice_getConnection() method now correctly returns a connection if connection caching is disabled (it previously returned a null connection).

  • The iOS SSL transport is now based on the same implementation as macOS. Most of the functionality supported on macOS is now also supported on iOS. There are still few limitations however:

    • the checkValidity, getNotBefore, getNotAfter methods are not supported on the IceSSL::Certificate class.

    • only PKCS12 certificates are supported (no support for PEM).

  • Added support for iAP transport to allow iOS clients to communicate with connected accessories.

  • The Ice::ConnectionInfo sndSize and rcvSize data members have been moved to the TCP and UDP connection info classes. The Ice::WSEndpointInfo and IceSSL::EndpointInfo classes no longer inherit Ice::IPConnectionInfo and instead directly extend Ice::ConnectionInfo. IP connection information can still be retrieved by accessing the connection information object stored with the new underlying data member.

  • IceGrid and IceStorm now use LMDB for their persistent storage instead of Freeze/BerkeleyDB.

  • Added command line tools, icegriddb and icestormdb, to import/export the IceGrid and IceStorm databases.

  • Added support for two additional IceGrid variables: server.data and service.data. These variables point to server and service specific data directories created by IceGrid on the node. These data directories are automatically removed by IceGrid if you remove the server from the deployment.

    For consistency, the node.datadir variable has been deprecated, use the node.data variable instead.

  • Added the new metadata tag delegate for local interfaces with one operation. Interfaces with this metadata will be generated as a std::function in C++11, delegate in C#, FunctionalInterface in Java, function callback in JavaScript, block in Objective-C, function/lambda in Python. Other language mappings keep their default behavior.

  • ObjectFactory has been deprecated in favor of the new local interface ValueFactory. Communicator operations addObjectFactoryand findObjectFactory have been deprecated in favor of similar operations on the new interface ValueFactoryManager.

  • Renamed local interface metadata async to async-oneway.

  • Replaced ConnectionCallback by delegates CloseCallback and HeartbeatCallback. Also replaced setCallback by setCloseCallback and setHeartbeatCallback on the Connection interface.

  • Updating Windows build system to use MSBuild instead of nmake.

  • Changed the parsing of hex escape sequences (\x....) in Slice string literals: the parsing now stops after 2 hex digits. For example, \x0ab is now read as '\x0a' followed by 'b'. Previously all the hex digits where read like in C++.

  • Stringified identities and proxies now support non-ASCII characters and universal character names (\unnnn and \Unnnnnnnn). See the property Ice.ToStringMode and the static function/method identityToString.

Java Changes

  • Fixed a bug where unmarshaling Ice objects was really slow when using compact type IDs.

Objective-C Changes

  • Fixed a bug where optional object dictionary parameters would trigger an assert on marshaling.

PHP Changes

  • Added support for PHP 7.
